92 Viscount Cole and Mr, Philip Egerton's Account of the 



diate inspection will determine the moment when the instru- 

 ment is to be changed ; in the other case the length of the 

 time elapsed can be the only guide. With this use of the in- 

 strument I became acquainted through Prof. Gauss's first 

 trials of heliotropic observations, before the proper instru- 

 ments which he had devised were finished. Trials made at a 

 distance of nine (41^ English) miles, in which the sun was seen 

 directly, succeeded perfectly ; and even trials made at a distance 

 of fourteen (64i English) miles under the most unfavourable 

 circumstances, the sun being seen by reflexion immediately 

 upon rising, gave a satisfactory result.

XIV. Viscount Cole and Mr. Philip Egerton's Account of 

 the Destruction of the Cane of Kiihloch, in Franconia. 



Dear Sir, Oxford, July 8, 1829. 



T BEG to make public, through your Journal, an account 

 -*■ I have just received from Lord Cole and Philip Egerton, 

 Esq. of the recent destruction of the most interesting and cu- 

 rious deposit of organic remains in Germany ; viz. that in the 

 cave of Kuhloch in Franconia, and also of another cave of 

 less importance adjacent to it. 



In my Heliquice DiliiviancE (page 137 et seq. and PI. 18), 

 I have given a detailed description and drawing of the Cave 

 of Kiihloch*. The enormous quantity of black animal earth de- 

 rived from pulverized bones, constituted its peculiar feature ; 

 and I have endeavoured to explain the causes of this peculia- 

 rity by the form and features of its entrance, which, as they 

 have now been nearly obliterated, and may hereafter be found 

 not to correspond with my description, I wish to record the 

 fact and time of their obliteration, by the publication of the fol- 

 lowing letter. And remain, 



Your obedient servant, 



To R. Tat/lor, Esq. William Buckland. 



My dear Sir, Schaffliausen, June 26, 1829. 



Lord Cole and myself are just returned to Schaffliausen 

 from a three weeks visit to the antediluvian caverns of Fran- 

 conia; and knowing the great interest you feel in their welfare, 

 I write to inform you of the melancholy fact of the total de- 

 struction of the deposit of bones in the caves of Kiihloch and 



* Dr. Buckland's account of tlie cave of Kiihloch will be found in Phil. 

 Mag. vol. Ixii. p. 112; and also, together with M. Chevreul's analysis of 

 the animal earth, in Ann. Phil. N.S. vol. ix. p. 284. — Eurr.
